I have a project created with seam-gen (using RHDS, same like in console). In my test folder I have created a test class and a testng.xml.

If I choose the class and use "run as - TestNG Test" the result is Total tests run: 0, Failures: 0, Skips: 0

If I use build.xml -> test: You need to specify at least one testng.xml or one class

or if I use "testng.xml -> run as -> TestNG Suite" here the error

Hey guys, big thanks to your work. Seam rocks. But can you please update/refresh documentation. The correct approach is not clear how to use seam tests.
